EDNVARD SAMUEL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO WVILLIAM -WHARTON, J R., AND COMPANY, (INCORPORATED) OF SAME PLACE.

-PERMANENT WAY OF RAILWAYS.

SPECIFICATION forming part. of Letters Patent No. 366,031, dated July 5, 1887.

Application filed Apr-i123, 1887.

To all whom, it may concern.-

- Be it known'that I, EDWARD SAMUEL, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Permanent \Vays of Railways, of which the following is a specification.

One object of my invention is to so connect railroad-chairs to their supports that they may be adjusted thereon, but when secured will be firmly locked in place, a further obmetal chair and a metal support therefor are secured together in contact with each other.

In the accompanying drawings, Figure 1v is a transverse section of a conduit railway structure, illustrating my improvement. Fig. 2 is a perspective view of a chair, part of the support and lilling-pieee detached. Fig. 3 is a side view, partly in section, showing the positions of the parts before the chair is socured to the support. Fig. 4 is a similar view showing the parts after the chair has been se cured, and Fig. 5 is a View showing the chair secured to a wooden cross-tie.

In Fig. l I have shown an electrical or cable conduit, with arms A A, which support the rails and act as cross-ties, although it should be understood that any cross-tie or base-plate may be used in carrying out my invention. The arm A has a plate, a, on which rests the chair B, the latter having a base, 1), corresponding to the supporting-plate a, and a vertical standard, 0, to which is secured the web (Z of the rail In the under side of the base-plate b of the chair B are grooves e ctwo in thepresentinstance-extending parallel with the rail or transversely to the line of lateral thrust on the chair, and in the upper face of the supporting-plate a of the arm A are groovesff, preferably located directly beneath the grooves in the under side of the chair B.

Between the base-plate of the chair and the supporting-plate a is inserted a slab, E, of wood, lead, rubber, or other elastic, semi-elastic, or flexible material, which acts as de scribed hereinafter, to form both a chair-lock and a sound-deadener.

The base-plate of the chair, the supporting Serial No. 235,877. (No model.)

plate a, and the slab or filling-piece E are provided with openings through which securingbolts z i are passed, the openings in the plate a or in the base-plate I). being elongated in order that the chair may be adjusted laterally in respect to the support. When the parts are in the positions shown, in Fig. 3, the bolts are loose and the chair is not secured in position, but is free to-be adjusted in order that the track may have the proper gage. IVhen the chair has been properly adjusted, however, the nuts on the bolts 1' are screwed tight, and pressure is thus exerted upon the material of which the filling-piece E is made, and, owing to the character of this material, it will be forced into the grooves e and f of the support ing-plate a and base-plate b, and firmly lock them together, so far as regards lateral mo tion of one upon the other, while at the same time it tends to exert upon the nutsa pressure which will prevent them from beingloosened,

and it acts as an absorbent of sound and serves as a cushion between the chair and its snpporting-plate.

In Fig. 5 I have shown the chair and fillingpiece used with a grooved wooden erosstie. In this case spikes may be used instead of bolts; but the latter are preferred.

I claim as my invention- 1. The combination of the support having grooves in its upper surface, the chair having grooves in its under surface, and an inter posed fillingpiece, E, adapted to be forced into the grooves when the chair is secured to the support, all substantially as set forth.

2. The combination of the support having grooves in its upper surface, a chair having grooves in its under surface, an interposed filling-piece, and securing-bolts adapted to openings in said support and chair, the openings in one of said parts being elongated, all substantially as specified.

In testimony whereof I have signed my name to this specification-in the presence of two sub scribing witnesses.

'ED'WD. SAMUEL.
